General description
Potassium nitrosodisulfonate is an oxidizing reagent that can be used to convert phenols, naphthols, and anilines to quinones, benzylic alcohols to aldehydes or ketones, and amino acids to α-keto acids. It can also be used for the preparation of heterocyclic quinones and oxidative aromatization.
Application
Potassium nitrosodisulfonate can be used as an oxidizing reagent for the oxidation of:
- Aromatic amines to their corresponding quinones.
- Hydroethidine to 2-hydroxyethidium.
- Tyrosine to o-quinones.
